Hi ,


Attached a test results we have done with the AD9361 and the script we used during the test.


Our center freq was 2400MHz.


We transmitted NCO with freq of -4MHz.


We measured DC spur at -22dbc.


What is the reason for this spur?


Does different FIR may help?


Does BB DC offset tracking or RF offset tracking or Tx quad cal or any other cal may help?
